China said that it’s put 1,541 people infected with the novel coronavirus but who don’t have symptoms under observation as of March 30, a much-anticipated announcement which helps provide a deeper picture of the scale of the country’s epidemic.

It was unclear from the statement if that number was only of people currently in medical quarantine or if it included those who were symptom-free but have since recovered and been released. Of the cases, 205 were found among people entering China from overseas, according to a statement on China’s National Health Commission website.

China’s total count of confirmed Covid-19 infections stands at more than 81,000, but the vast majority have recovered and been released. The country still has 2,161 cases in hospital as of March 30, according to health commission data.
